President Medvedev has just fired the Deputy Commander of the Federal Security Service. Furthermore, a new law "On Police" has just been passed. Finally, President Medvedev has just held a conference with commanders of all the security services where he made a very strong speech about the need to bring order, discipline and ethics for all the security services. He threatened all the commanders with being immediately fired if they did not immediately implement these rules.
Looks like the Russian President is determined to use the bombing of the Domodedovo airport as an opportunity to seriously shake up the security services.
